The invention relates to a device for automatically setting the counters of multiplecounter calculating and registering machines.

In multiple-counter calculating and registering machines provided with a printing attachment the -counters have been arranged on a drum which is step by step turned by the paper carriage through one or several shifting values.

According to the invention the device intended for setting such counters is designed I in such a Way that the intermittent rotation of the counter drum is accomplished by a transmission element (50) which, on one hand, is positively connected to the countei1 drum and, on the other hand, is controlled by the raising edge of the paper carriage which edge may be smooth or stepped.

The advantage of the invention consists in that clips and stops on the paper carriage the same as the switching elements engaging with the clips or stops are dispensed with so that setting the counters is rendered partieularly simple and reliable.

' In the accompanying drawings an instance of execution of the counter control accord- `ing to the invention is shown by way of example, in which drawings Fig. l is a sideuelevation and Fig. 2 is a plan'view.

Below the base plate 1 of the machine and between the drop-hanger bearings 2 and 3 the counter drum is arranged on the axle 7 and consists of the two discs 4 and 5 fastened to a hub 6. Between the dises 4 and 5 sixteen counters 15 blocked by rods 9 while out of work are mounted on axles 8. The blocking rods 9 are guided in slots of the discs 4 and 5 and are drawn by springs 1() into their working position. At one end the springs are attached to the dises 4 and 5 and at the other end they engage with atie 11 reaching over two adjacent rods so that one spring always simultaneously yacts upon 'two blocking rods. i

Type carriers 12 are influenced by springs 13 and are moving up and down in a wellknown manner while the machine is in operation. To their lower end are attached driving racks 14 for the counters 15. ln their bottom portion these racks are provided with a slot 16 through which extends a cross bar 17 carrying a guiding comb 18 for the spacing of the racks. r1`he cross bar is supported by two cheeks 19 and 20 which are pivotally mounted at a lixed point 21 of the machine. The turned ends of the cross bar 17 extend through the cheeks 19, 2() and carry links 22, 23 connected to small links 24, 2o and forming each a toggle with the latter. The small links are pivotally mounted at 26 on the drop-hanger bearings 2, 2l. 'lhe shaft 27 carries two levers 28 which by the medium of the cranked links 29 are also con nected to the togglcs 22, 24 and 23, 25. By its turned journals the shaft 27 is rockingly mounted in the side frames of the machinev and is imparted a reciprocate motion during each operation of the machine. ln the position shown by Fig. l the togglcs are forming a lock so that the driving racks 14 have been brought into engagement with the counting gears. When now the shaft 27 is turned in the direction of the arrow (Fig. 1) the toggles 24, 25 are moved upwards so that the links 22, 23 push the driving racks 14 out of engagement with the counting gears. Between the rocking cheeks 19, 20 is mounted across bar 3() which carries the shitting pawls 31 and it is obvious that they also move out of engagement with the counting gears as soon as the driving racks 14 are brought out of engagement.

The figures inserted in the machine are printed by types 32 on tlie platen which is nrounted between the two end plates 39, 40 of the paper carriage. '1`he paper carriage is guided by two rails 34,37 the first of which is fastened to theffside frames of the machine while the rail 37 is slidably mounted on balls 35, 36 in order to move along the rail 34; The carriage is'subject to the action of a spring and a tabulator device is arranged so that the i carriage may jump from column to column in a well-known manner as the machine is being operated.

Moreover a lever 38 is provided to render the tabulatorldevice inoperative so that the paper carriage may also be shifted at will manually.

To the lower end of the end plates 39, 40 of the paper carriage are fastened angle pieces 41, 42 which carryV an easily interchangeable plate 43 provided with steps 44 (Fig. 2). Below this plate a lever 45 is pvotally mounted at a fixed point 46 of the machine and it carries a roller 47 which is continuously pressed against the plate 43 by the tension of the spring 48. The free end of the lever 45 is forked and carries a shaped piece 49 revoluble on journals it is provided with. A rack 50 one end of which is also forked is rockingly connected to the shaped piece 49 while the toothed end'meshes with a toothed wheel 51 pinned Ato the axle'7 of the counter drum 4 6. A guiding block 52 always maintains the rack 50 in its correct position in respect to the toothed wheel 51. When now the paper carriage is displaced in the direction ot' the arrow P (Fig. 2), the roller 47 jumps from one step of the plate 43 to another under the tension ofthe spring 48 and it is obvious that in this way the drum is turned through the medium of the rack 50 and the toothed wheel 51.v Thus the roller 47 moves from one step to another, the next counter of the drum will be broughtv into its operative position.

While the paper carriage is moving the driving racks 14 are out of engagement with the counting gears 15. The rocking cheeks 19, 20 carry guiding pieces 53, 54 so designed that with their forked ends they grip the counter axles 8, as soon as the driving racks 14 are brought again into engagement by means of the rocking arms 19, 20.

The steps 44 of the plate 43 may be adjustable by hand but in the present case it is preferable to use a special plate for every work which is likely to be repeated so that tedious adjustments are dispensed with. For instance plate 43 as shown in Fig. 2 is in-v tended for controlling thirteen counters. The length of the steps depends on the width of the columns adjusted on the schedule. InL

stead of steps 44 an inclined surface or av curve could readily be made use of. Below the plate 43 is arranged another straight rod or guar-'d 55 which is supported by studs 56, 57 extending through Z-shaped slots formed in the said rod. A bell crank lever 58 is pivotally mounted at 59 on the plate 43 and its forked arm encloses a pin 60 riveted to the rod 55.A

The modus operandi of the device described is as follows:-

In Fig. 2 the counter drum is shown in its operative position. As soon as it has taken up the figure determined by the key pressed down the paper carriage is shifted which now jumps in the direction of the arrow P (Fig. 2) so that the roller 47 slides tothe subsequent step of the plate 43. In this way the next counter is brought into its operative position and the operation is continued in the same manner. Vith the last movement of the paper carriage the roller 47 slides from the step 44 down to the narrow end of the plate 43 and thereby presses back the projecting arm of the bell crank lever 58 so that the rod 55 gets into the position shown by dotted lines in Fig. 2. The steps of the plate 43 will then be covered by the rod 55 so that the roll 47 is able to draw back the lever 45 without jerks into its initial position when the carriage is returned. By means ot the transmission gearing 50 and 51 the drum is turned back and all parts are made to assume the position shown by Fig. 1.

lThe paper carriage can be returned either by hand with the aid of the lever 38 or in a well-known way by the motor drive of the machine. In the case ot' machines of this type it is kno-wn to bring the driving elements out of engagement with the counters prior to the return movement of the carriage which is accomplished by the motion of the carriage itself. Moreover there are well-known devices by which the paper carriage can be returned into its neutral position vtrom any other posit-ion or by which the paper carriage is caused to run over a definite portion of this distance.

The present invention also provides for a handle 61 (Fig. 2) by which the paper earriage may be returned either tot-ally or any distance desired and this handle is so connected to the counter setting device that the driving racks 14 of the counters are brought directly out of engagement with the latter as soon as the handle is used. rl`he handle 61 is guided below the base plate 1 by means of studs 62 and slots 62 with which its side 63 is provided, to which it is connected by the bridge 64. A spring 65 is hooked into the bent end of the side plate 63 and tends to always maintain the parts in the position shown in` Fig..1. An arm 66 of the plate l63 is connected by link 68 to a bell crank lever v67 The said crank lever is pivotal y mounted on a stud 69 below the base plate of the machine and its other arm is connected to an angularly bent lilik 70, 71 the other end of which is attached by means of a slot and a screw to one arm 7 2 of the lever 28.

When the handle 61 (Fig. 2) is pulled back lin the direction of the arrow this movement is. transmitted by the link 68 and the crank lever 67 to the link.70, 71 and lever 28 so that the latter is turned in the direction of the arrow W (Fig. 1) and by means of its link 29y opens the toggle 24, 22. In this way the driving racks 14 are brought-out of engagement with the counting gears as was already described. The motion of the handle 61 being continued as far aS the slots 62 permit, the motor-driven carriage return device is switched on in a manner otherwise well- Lemme known --so that the carriage is now returnedi The slot arranged in the link 71 is intended for keeping the parts 67, 68 and 61 uninfiuenced during the machine operation whenthel driving racks 14 are oscillated by the shaft 27.

The screw of the arm 72 holding the link 71 also has attached thereto a connecting rod 73, the hooked end 74 of which rod bears against the rear of a bar 75 connected to arms 76 which are rigidly fastened to a shaft 77.

To this shaft which, the same as shaft 75, extends overthe Whole 'Width of the paper carriage is pinned the handle 38.- It is obvious that a movement of the handle 38 results in the shaft 27 being-turned through the link-73 so that the driving racks 14 are also brought out of engagement as soon as the paper carriage is moved by hand.

WhatiI claim as my invention, and desire to secure by Letters Patent, isi A device for setting the counters of multiple calculating and registering machines including a paper carriage and a drum having counters mounted thereon, said paper carriage including a plate member having a. stepped edge, a transmission element pivoted at one end to a fixed part of the machine, a positive driving connection between the free end of the transmission element and the drum, a roller mounted on an intermediate part of the transmission element and adapted to Vride on the stepped'edge of the plate member to impart a step by step movementto the transmission and through the positive driving connection to the drum, a guard displaceably mounted on the plate member of the carriage adjacent to the stepped edge of said plate member, and means actuated by the roller for moving the guard over the stepped edge of the plate member prior to the return movement of the carriage to prevent said roller carried by the transmission element from riding on the stepped edge of the plate member during the return movement of the carriage.

In testimony whereof I aiiix my signature.
